 We show in this  tutorial how GetDP takes advantage of global quantities and the associated global basis functions
    * to reduce the number of unknowns
    * to deal with floating potentials
-   * to compute efficiently the electrode charges, 
+   * to compute efficiently the electrode charges,
      which are the energy duals of the electrode voltages
    * to compute output quantities (charges, armature voltages, capacitances, ...)
      that can be immediately used in a external circuit.
